Due to backorder of reagents from our supplier, Galectin-3 testing will be delayed for approximately 4-6 weeks. All Galectin-3 samples will be stored at frozen stability, and results will be available once testing is resumed. Please continue sample collection as requested by the provider.

Clinical significance: A galectin-3 test may be ordered for the identification of individuals with chronic heart failure at elevated risk of disease progression.
Limitations: Hemolysis can falsely elevate results. Presence of human anti-mouse antibodies (HAMA) or rheumatoid factor (RF) greater than 50 IU/mL, , or specimens with high levels of gamma globulins (≥2.5 g/dL), may cause falsely elevated results. Galectin-3 results should be interpreted with caution in patients with a history of therapeutic use of murine monoclonal antibodies (IgG) or their fragments, who have known autoimmune disorders, or who have diseases associated with hyperglobulinemia such as multiple myeloma. Levels of galectin-3 in the blood may be increased in patients with certain forms of advanced cancer and other conditions associated with organ fibrosis. Results should be interpreted with caution in such patients.
